China’s carbon trading market has been carried out pilot construction in 7 provinces and cities. Experimental results show that the implementation of carbon trading market in China is effective and feasible. China’s carbon trading pilots have some unique features，including a specific cap combined with a flexible structure，an allowance allocation rule based on historical emissions combined with some benchmarking，a free allowance distribution arrangement combined with some level of auction，and pre-determined quotas combined with ex-post allowance adjustments. However，due to the short preparation period and the lack of adequate emissions data，the pilot carbon trading market is also facing some particular issues，such as excess allowances，whipping the ox，double calculation，the limited benchmarking，the low proportion of auction，etc. The experience gained from the pilot carbon market has laid a good foundation for the construction of the national carbon market. In promoting the construction of the national carbon market，China must attach great importance to the legislation of carbon trading management，emission data statistics and pilot seamless convergence problem.
